Function check
Carry out the function check on page 5.
Lubrication
Lubricate the coupling weekly with VBG mechanism oil
or similar thin oil. For the maximum effect, the coupling
should be open when it is being lubricated.
VBG do not recommend the use of central greasing
systems.
•
Lubrication points (see adjacent drawing).
Mounting of drawbeam sleeve
• Mount the drawbeam sleeve (a) with four screws as
per the drawing. Flat washers with a minimum hardness
of 200 HB must be under both bolt head and nut.
Tightening torque M20 quality 8.8 (dry): 370 Nm.
Mounting of coupling
• Lubricate the coupling jaw (b) and all its threads with
grease. This prevents rust and makes future service
work easier.
• Fit the attachment parts as shown in the fi gure. Fit the
bar spacer washers on the drawbeam sleeve collar so
that the dimension 5–8,5 mm is achieved. The number
of washers depends on the thickness of the drawbeam,
and the 10 mm washer should be outermost. See fi gure.
Mount accessories such as the coupling mouth exten-
sion (c) according to the drawing.
Tightening torque castellated nut 1500 – 2000 Nm.
